Since nitre was an important component of gunpowder, it used to be common, during wars, to save one's urine. As for using it as a fertilizer, I would have a couple of reservations. First, urine, as it comes out of the body, is very strong. Using it straight would be likely to "burn" the plants. (Although, in medievel times, the "lords of the city" had their fields close to the town so that the "commoners" would have to cross them to get to their fields, their oxen leaving their dropping to fertilize the fields.) Also urine typically contains dangerous bacteria; one of the purposes of urine being to get bacteria out of the body.
